Deep JWST/NIRCam imaging of Supernova 1987A
Mikako Matsuura, M. Boyer, Richard G. Arendt +46
JWST/NIRCam obtained high angular-resolution (0.05-0.1''), deep near-infrared 1--5 micron imaging of Supernova (SN) 1987A taken 35 years after the explosion. In the NIRCam images,…
The Re-Acceleration of the Shock Wave in the Radio Remnant of SN 1987A
Yvette Cendes, Bryan Gaensler, Chi-Yung Ng +3
We report on updated radio imaging observations of the radio remnant of Supernova 1987A (SN 1987A) at 9 GHz, taken with the Australia Telescope Compact Array (ATCA), covering a 25-…
ALMA spectral survey of Supernova 1987A --- molecular inventory, chemistry, dynamics and explosive nucleosynthesis
M. Matsuura, R. Indebetouw, S. Woosley +26
We report the first molecular line survey of Supernova 1987A in the millimetre wavelength range. In the ALMA 210--300 and 340--360 GHz spectra, we detected cold (20--170 K) CO, 28S…
A stubbornly large mass of cold dust in the ejecta of Supernova 1987A
M. Matsuura, E. Dwek, M. J. Barlow +33
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 micron data and im…
Dust Production and Particle Acceleration in Supernova 1987A Revealed with ALMA
R. Indebetouw, M. Matsuura, E. Dwek +23
Supernova (SN) explosions are crucial engines driving the evolution of galaxies by shock heating gas, increasing the metallicity, creating dust, and accelerating energetic particle…
Carbon Monoxide in the Cold Debris of Supernova 1987A
J. Kamenetzky, R. McCray, R. Indebetouw +27
We report spectroscopic and imaging observations of rotational transitions of cold CO and SiO in the ejecta of SN1987A, the first such emission detected in a supernova remnant. In…
The remnant of SN1987A revealed at (sub-)mm wavelengths
Masha Lakicevic, Jacco Th. van Loon, Ferdinando Patat +2
Context: Supernova 1987A (SN1987A) exploded in the Large Magellanic Cloud (LMC). Its proximity and rapid evolution makes it a unique case study of the early phases in the developme…
